Why can't LED indoor screen be used outdoors

2022/09/23

  LED display screen is widely used in daily life. If it is subdivided into many categories, it can be divided into indoor LED display screen and outdoor LED display screen from the perspective of environmental configuration. Some customers have purchased indoor LED displays. After using them for a period of time, the company has activities that need to be used outdoors. In order to save costs, can you move the indoor LED displays to outdoor use?


  Customers with this idea do not know about LED display. Xiaobian can give you a positive answer. It is unrealistic to change the indoor LED display to outdoor use for the following reasons. Please listen to Xiaobian carefully.

1、 Brightness


The brightness of indoor LED display screen is not required to be high. The dynamic scanning circuit is used, while the outdoor LED display screen has high brightness. The static scanning circuit is used, and the hardware difference between the two is large. The brightness of the indoor screen is ten to dozens of times that of the outdoor screen. Placing the indoor screen outdoors is just like placing the TV outdoors. The brightness is insufficient.


2、 Waterproofness


The adaptability of outdoor screen to the environment is much higher than that of indoor screen. The outdoor screen must be protected from rain, direct sunlight, dust, high temperature, wind and lightning, but these problems need not be considered for the indoor screen. The indoor LED display screen structure requires no waterproof or simple waterproof treatment, so the requirements on the box structure itself are different.


3、 Dust proof layer limit:


Dust is the key factor to reduce the commodity rate of LED displays and accelerate the commodity embrittlement. Outdoor LED displays need to be dust-proof structure and dust-proof filter according to the design scheme to maintain the commodities.


4、 Sight distance limitation


The indoor full-color LED display screen is required to have a short viewing distance, and its models and specifications are generally P0.9, P1.2, P1.5, P1.8, P2, P2.5, P3, so its area is generally within 30 m2, while the outdoor LED display screen is required to have a long viewing distance, and its models are generally P4, P6, P8, so its area is generally larger than 30 m2.


   The above reasons are summarized by the small editor: the indoor LED display screen and the outdoor LED display screen are different in brightness, waterproof, dust-proof treatment, model selection and other aspects, resulting in different raw materials, accessories, boxes and other hardware at the beginning of production, so try not to change, and the effect will only be worse if you change!
